Code: 8964. In our factories, we produce an dimple membrane in recycled HDPE, in rolls, suitable for protecting underground walls , between the insulation or the waterproof sheath and the earth.

The recycled HDPE dimple membrane has conical rises equal to 8 mm. which serve to maintain a distance between the element to be protected, the wall, and the external earth.

The HDPE dimple membrane has a compressive strength of approximately 250 KN/m2, encloses in the air chamber that forms between the sheet and the wall a volume of air of about 5.2 liters per m2 and has a resistance to thermal shock whose temperatures can fluctuate between -30 and + 80 °C.
